Squirrels, like deer, are most active early and late. They'll move about more on calm days, preferring to keep a low profile when high winds rock the treetops. Pick a spot in easy range of a den tree or feeding area. Wear camo, sit against a trunk, and be the tree. Watch for dipping, swaying branches, swishing leaves, and even the fall of cuttings to the forest floor. Listen for the gnawing sound of buckteeth on nutshells, of claws skittering on bark, or the startlingly loud rustle of leaves. Remain still after you shoot; often, the pop of a .22 or even the louder boom of a shotgun won't disturb the squirrels for long, and you can take several from the same stand.
